Ortiz-Echage would later win the Prix de Rome, a scholarship for arts students, in 1904.

Included in the sale is a photograph from 1948 of Lucien's son, Sacha Guitry, starring in The Comedian.

Verifying this painting's provenance, Ortiz-Echage's portrait of Lucien Guitry is visible in the paintings background behind Sacha sitting at his desk. Depictions of Frans Hals and a Toulouse-Lautrec are also visible.

This fascinating piece of French theatre history will undoubtedly attract bidders from both France and abroad when it auctions in November.
